Adoptee struggling

Adoptee: Identity struggles, self esteem, maintaining relationships, and depression Hey everyone. I was hoping to start a narrative, in hope to mitigate some of my depression and loneliness. I was adopted at birth, in the state of Texas, by two of the most loving and kind parents I could ever know. They are truly beautiful souls. I never remember them telling me that I was adopted. They told me when I was very young, and it has felt like I’ve always just known. They are hard working, successful parents who more than provided anything and everything I wanted or needed. I have been guided and taught well, and believe that I am genuinely a good man today. I followed in their footsteps in regards to education and am currently finishing college. They set a fantastic standard of success that I had the fortune of learning. However, I have always had a sadness about me. I remember when I was in 5th grade having this sort of awakening of the sadness. I realized what adoption actually was, and that I am different than most. I felt abandoned and rejected. I wasn’t a shy kid either, I knew just about everyone at school and was very outgoing. But now that I am 26, there are definitely struggles that I cope with that I thought I could share. Every single day I think of my adoption, and my birth parents. It saddens me. Everyone tells me it shouldn’t, but they couldn’t understand the feeling of being adopted. I struggle with self esteem, and have trust issues as well. I try my best to receive constructive criticism, but it just cuts too deep sometimes. Most recently, a friend of mine from college made a “joke” when it really just hurt my feelings. Currently am dealing with the effects of the comment he made, so I sought out the psychology of adoption, and was lead to this page. I hope I hear some responses, as I am feeling like no one can relate, or can give me insight or help on my feelings, or adoption. Thank you.
